I work with a wide range of model types, sculpture, engineering, rockwork, architecture and every other type imaginable. All which have to be brought out into the physical world. This often requires that I hop back and forth between programs and import files. Having the control over meshes that the version 6, C-mesh command is missed.
Also there was a plug in at one time 3 Point alignment that no longer functions. That used to be a huge help when I needed to import models and get them in the right place.
Thanks for listening,
